SPEClFICATION forming part of Letters Patent No. 601,683, dated April 5`, 1898. Application nea October 1s, 1897. serai No. 655,551. (No model.)

Be it known that I, DE WANE B. SMITH, of Deerfield, inthe county of Oneida and State of New York, have invented certain new and useful Improvements in Swivel Hose-Couplings; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Figure l shows the swivel-couplingin connection with a piece of hose attached. Fig. 2 shows a longitudinal section of the swivel. Fig. 3 shows a longitudinal section on an en- Fig. 4 shows a partial longitudinal section on a further enlarged scale.

The body l of the swivel is tubular and is provided with an externally-screw-threaded end l and a knurled enlargement lb, by means of which the body may be readily rotated with the fingers. The body on the opposite side of the enlargement from the screwthread is arranged to receive a sleeve 2. The sleeve 2 is provided with a substantially square end at one end adapted to engage with one side of the enlargement 1b and at the other is provided with an undercut round 2a and an overcut round 2b. The end of the tubular body is iiared, as shown at a, to conform to the undercut round 2 of the sleeve, and the edge or end of the flare is formed to a completement of the outside round 2b of the end of the sleeve 2.

The hose 4,having in itself a certain amount of contractibility, is slipped over the end of the swivel and secured to the sleeve 2 by wiring 'w into grooves provided on the exterior vring 3 to pack this joint.

'ed end will work the sleeve toward the left as the device is shown in the drawings and 5o close the joint tightly at this end. j

This swivel-couplin g is particularly intend- 'ed for use with bicycle-pumps and is attached to or detached from the pneumatic-tire lixture byaotating the body of the device so as to screw the swivel to or unscrew it from the tireiixture. There may be provided a packing- What l claimas new, and desire tosecure by Letters Patent,'isp j l. The combination in a hose-swivel of the tubular body having one end screw-threaded, and the other flared, of a sleeve mounted on the body and having a rounded end conforming on the exterior with the flared end of the body, substantially as set forth. 2. The combination with the hose of a` swivel consisting of a tubular body having a screw-thread at one end and flared at the other end, of a sleeve mounted on the body the end of the sleeve and flared end of the body being made to conform whereby the hose covers and closes the joint, substantially as set forth.

In witness whereof I have affixed my signa-v ture in presence of two witnesses.
